An opportunity to buy on support

the reversal pattern could be described as i have on the chart, as it gapped both into, and out of, the pattern..
the trade i have posted on the chart i will only take on a gap-closing pullback to the support line around $54
followed by a bullish 15-min to 30-min candle. not sure if this is the best way to enter, and my last position (a losing
long on $BABA) was also entered in this fashion. however, i will try again on GPRO .
